2 Fixed a bug with libntfs-3g extraction present since v1.8.1. Sometimes,
3 some Microsoft software would not correctly recognize data in the
4 resulting filesystem. Users of the (UNIX-only) NTFS-3g based WIM
5 extraction support should not use wimlib v1.8.1 or wimlib v1.8.2.
7 Made some small improvements to the compression algorithms.
9 Improved handling of WIM XML data and added two new API functions:
10 wimlib_get_image_property() and wimlib_set_image_property().
12 Added support for (unsafe) in-place compaction of WIM files.
14 Several improvements to System Compression (compact mode) support:
16 wof.sys (or wofadk.sys) is now automatically attached to the
17 target volume if needed.
19 Compact-mode extractions now work correctly with wofadk.sys on
20 older versions of Windows.
22 For compatibility with the Windows bootloader, the requested
23 compression format now is overridden on certain files.
26 This release primarily contains various minor bug fixes and
27 improvements, including:
29 Improved handling of deep directory structures.
31 Fixed a bug where on 32-bit systems, the library could enter an
32 infinite loop if a WIM file was malformed in a specific way.
34 Added a workaround for a case where libntfs-3g may report
35 duplicate streams in an NTFS file.
37 Windows symbolic links and junctions in mounted WIM images are
38 now automatically rewritten to be valid in the mounted location.
40 Reparse point fixes: correctly handle the "ReparseReserved"
41 field, and correctly handle "empty" (data-less) reparse points.
43 On Windows, wimlib now acquires SeManageVolumePrivilege, which
44 is needed to create externally backed files using the
47 Improved validation of filenames.
49 Improved LZMS decompression speed.
51 The configure script now honors alternate pkg-config settings.
53 Links have been updated to point to the new website.
55 In addition, experimental support has been added for compressing
56 extracted files using System Compression on Windows 10. This
57 functionality is available through the new '--compact' option to
58 'wimapply' and 'wimextract' as well as new library flags.
61 Fixed a bug in the LZX decompressor: malicious input data could cause
62 out of bounds writes to memory (since wimlib v1.2.2).
64 The output of the 'wiminfo' command now consolidates various boolean
65 flags (such as "Relative path junction") into a single line.
67 A file can now have both an unnamed data stream ("file contents") and a
68 reparse point stream. Such files can exist as a result of the use of
69 certain Windows features, such as offline storage, including "OneDrive".
70 wimlib will now store and restore both streams on Windows as well as in
71 NTFS-3g mode. Microsoft's WIMGAPI also has this behavior.
73 On Windows, named data streams of encrypted files are no longer stored
74 twice in WIM archives.
76 On Windows, named data streams are now correctly extracted to existing
77 "readonly" directories. Before, an error would be reported.
79 On Windows, it is now possible to do a "WIMBoot mode" extraction with
80 non-standalone WIMs such as delta WIMs.
82 On Windows, when doing an extraction in "WIMBoot mode", files larger
83 than 4 gigabytes are now never extracted as externally backed. This
84 works around a bug in Microsoft's "WOF" driver.
86 The '--enable-verify-compression' configure option has been removed. If
87 you want to verify a WIM file, use the 'wimverify' program.
89 The way the "file count", "directory count", "total bytes", and "hard
90 link bytes" image statistics (stored in the WIM XML data) is calculated
91 has been slightly changed.
93 In mounted WIM images, the disk usage provided for each file (st_blocks)
94 is now the compressed size rather than the uncompressed size.
96 The performance of the NTFS-3g and Windows capture modes has been
99 On UNIX-like systems, symbolic links whose targets contain the backslash
100 character are now handled correctly (losslessly).
103 Improved the LZX compressor. It is now 15-20% faster than before and
104 provides a slightly better compression ratio.
106 Improved the LZMS compressor. It now provides a compression ratio
107 slightly better than WIMGAPI while still being faster and using slightly
110 The compression chunk size in solid resources, e.g. when capturing or
111 exporting a WIM file using the '--solid' option, now defaults to 64 MiB
112 (67108864 bytes) instead of 32 MiB (33554432 bytes). This provides a
113 better compression ratio and is the same value that WIMGAPI uses. The
114 memory usage is less than 50% higher than wimlib v1.7.4 and is slightly
115 lower than WIMGAPI's memory usage, but if it is too much, it is still
116 possible to choose a lower value, e.g. with the '--solid-chunk-size'
117 option to wimlib-imagex.
119 The '--chunk-size' and '--solid-chunk-size' options to wimlib-imagex now
120 accept the 'K', 'M', and 'G' suffixes.
122 Files are now sorted by name extension when creating a solid WIM file.
124 Fixed various issues related to capture/apply of EFS-encrypted files on
127 The file list printed by 'wimdir' is now sorted by the platform-specific
128 case sensitivity setting, rather than always case sensitively. This
129 also affects the library function wimlib_iterate_dir_tree().
131 On Windows, some error and warning messages have been improved.
134 The Windows binary distribution no longer contains third party DLLs.
135 These dependencies are instead compiled directly into the libwim DLL.
137 Added more fixes for wimlib on non-x86 architectures such as ARM.
139 Extracting files to a Windows PE in-memory filesystem no longer fails if
140 the target files do not yet exist.
142 Improved the performance of XPRESS compression and LZMS decompression.
144 Enabled SSSE3 accelerated SHA-1 computation in x86_64 Windows builds.
145 It will automatically be faster on newer Intel and AMD processors.
147 Removed the --with-imagex-progname and --enable-more-assertions
151 Fix for very slow export from solid WIM / ESD files.
153 Fix for LZX and LZMS algorithms on non-x86 architectures, such as ARM.
155 New progress message: WIMLIB_PROGRESS_MSG_HANDLE_ERROR. Applications
156 may use this to treat some types of errors as non-fatal.
158 The library now permits making in-memory changes to a WIMStruct backed
159 by a read-only WIM file.
161 Fixes for "WIMBoot" extraction mode (Windows only):
163 When not using the WOF driver, extraction no longer fails if the
164 disk containing the WIM file has too many partitions.
166 When matching patterns in [PrepopulateList], all hard links of
167 each file are now considered.
169 The system registry files are now automatically treated as being
170 in [PrepopulateList].
172 Added a hack to try to work around an intermittent bug in
173 Microsoft's WOF (Windows Overlay Filesystem) driver.
176 Made more improvements to the XPRESS, LZX, and LZMS compressors.
178 A number of improvements to the Windows port:
180 Fixes for setting short filenames.
182 Faster "WIMBoot" extraction.
184 Updated and slimmed down the dependent DLLs.
186 ACL inheritence bits are now restored.
188 Mandatory integrity labels are now backed up and restored.
190 Added a workaround for an issue where in rare cases, wimlib could create
191 a compressed data stream that could not be read correctly by Windows
192 after an extraction in "WIMBoot" mode.
195 Added file count progress data for
196 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE and
197 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
199 Added support for testing file exclusions via the user-provided
202 Some documentation improvements.
204 Made some clarifications to the license text in the COPYING file.
207 Made more improvements to the XPRESS, LZX, and LZMS compressors.
209 The default compression mode for wimcapture is now LZX compression in
210 its default mode, which is the same as '--compress=maximum'.
212 You can now specify an optional integer compression level to the
213 '--compress' option; e.g. '--compress=lzx:75'.
215 Made a minor change to the LZMS compressor and decompressor to fix an
216 incompatibility with the Microsoft implementation. In the unlikely
217 event that you created an LZMS-compressed WIM with wimlib v1.7.0 or
218 earlier and a checksum error is reported when extracting files from it
219 with wimlib v1.7.1, decompress it with v1.7.0 then compress it with
222 Added 'verify' subcommand to wimlib-imagex.
224 Notable library changes:
226 Custom compressor parameters have been removed from the library
227 in favor of the simpler level-based API.
229 Decompressor parameters have been removed entirely.
231 Library users can now specify a custom file for warning and
232 error messages to be sent to, rather than the default of
235 New progress messages:
236 WIMLIB_PROGRESS_MSG_EXTRACT_FILE_STRUCTURE,
237 WIMLIB_PROGRESS_MSG_EXTRACT_METADATA.
239 New function: wimlib_verify_wim().
242 Improved compression, decompression, and extraction performance.
244 Improved compatibility with version 3584 WIM / ESD files:
245 - Add support for reading and writing multiple solid blocks per
246 archive, which WIMGAPI/DISM can create when appending an image.
247 - Correctly create solid blocks larger than 4 GiB.
249 'add' commands passed to wimupdate will now replace existing
250 nondirectory files by default. Use the --no-replace option to get the
253 The license for the library now contains an exception that allows using
254 it under the LGPL. See the COPYING file for details.
256 In reparse-point fixup mode (the default for capture), symbolic links
257 and junctions that point outside the tree being captured are no longer
258 excluded from capture.
260 Added support for "WIMBoot" capture and extraction. See the
261 documentation for the new '--wimboot' option to wimcapture and wimapply
262 for more information.
264 On UNIX-like systems, you can now backup and restore device nodes, named
265 pipes, and sockets. In addition, 32-bit user and group IDs are now
268 The way that UNIX data is stored in WIM files has been changed. If you
269 captured any WIMs with the --unix-data option, to upgrade them you'll
270 need to apply them with --unix-data using wimlib-imagex v1.6.2, then
271 re-capture them with --unix-data using this version.
273 wimlib now understands tagged metadata items, such as object IDs, that
274 can be stored in WIM directory entries.
276 Removed the --hardlink and --symlink options to wimapply, since I don't
277 think they are too useful and they got in the way of improving the code.
279 WIMs will now retain their GUIDs when rebuilt (e.g. with wimoptimize).
281 The 'mkwinpeimg' script now supports writing the ISO image to standard
284 The <ARCH> element in WIM XML data is now exported correctly.
286 On Windows, sparse file attributes are no longer set on extracted files.
287 Oddly enough, this actually saves disk space in some cases.
289 On UNIX, configuring with --disable-xattr or --enable-xattr is no longer
290 supported. Mounting WIM images now always requires extended attribute
291 support. Use --without-fuse to disable support for mounting WIM images;
292 this will also disable the need for extended attribute support.
294 Configuring with --enable-ssse3-sha1 now works correctly.
296 The shared library version has been bumped up. The main
297 incompatibilities are:
299 - WIMLIB_COMPRESSION_TYPE_XPRESS is now 1 and
300 WIMLIB_COMPRESSION_TYPE_LZX is now 2 (so it's the same as
303 - User-provided progress functions are now registered using a
304 separate function, wimlib_register_progress_function(). The
305 'progress_func' argument to many functions no longer exists.
307 - The return value from user-provided progress functions is now
310 - A context argument has been added to the prototype of
311 user-provided progress functions.
313 - 'struct wimlib_capture_config' has been removed. The library
314 now takes the path to the configuration file directly. This
315 affects wimlib_add_image(), wimlib_add_image_multisource(),
316 and wimlib_update_image(). However, a NULL value passed in
317 the argument retains the same meaning.
319 - Removed deprecated functions: some (de)compression functions,
320 wimlib_extract_files(), and wimlib_print_metadata().
322 - Removed extraction flags: WIMLIB_EXTRACT_FLAG_HARDLINK,
323 WIMLIB_EXTRACT_FLAG_SYMLINK, WIMLIB_EXTRACT_FLAG_FILE_ORDER,
324 and WIMLIB_EXTRACT_FLAG_SEQUENTIAL.
326 - Removed some progress messages:
327 WIMLIB_PROGRESS_MSG_APPLY_TIMESTAMPS,
328 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_BEGIN,
329 WIMLIB_PROGRESS_MSG_EXTRACT_DIR_STRUCTURE_END. Numbering
332 - Removed some error codes. Numbering stays the same.
334 - Replaced WIMLIB_UNMOUNT_FLAG_LAZY with
335 WIMLIB_UNMOUNT_FLAG_FORCE.
337 - WIM paths passed to progress functions now have a leading
341 Case-insensitive comparisons of strings (e.g. filenames) containing
342 UTF-16 codepoints above 32767 are now done correctly.
344 Fixed build failure on Mac OS X.
346 wimunmount now provides the '--new-image' option to cause changes to a
347 read-write mounted image to be committed as a new image rather than as
348 an update of the mounted image. (The corresponding new library flag is
349 WIMLIB_UNMOUNT_FLAG_NEW_IMAGE.)
351 The LZMS ("recovery") compression chunk size, or "dictionary size", may
352 now be up to 1 GiB (1,073,741,824 bytes).
354 The performance of LZX ("maximum") and LZMS ("recovery") compression
355 with large chunk sizes has been slightly improved.
358 Stored files with size exactly 4 GiB (4,294,967,296 bytes) are now
359 decompressed correctly.
361 Fixed a bug in the LZX compressor introduced in v1.5.3. The bug
362 occurred in an unlikely case, and due to validity checks it did not
363 affect successfully created archives.
365 Fixed a minor compatibility issue with the LZMS compressor and
366 decompressor. This is *not* the default compression type and was only
367 introduced in v1.6.0. In the unlikely event that you created an
368 LZMS-compressed WIM with v1.6.0 and a checksum error is reported when
369 applying it with v1.6.1, decompress it with v1.6.0 then compress it with
372 Memory usage for LZMS and LZX compression has been decreased.
374 wimextract now allows wildcard characters in paths specified on the
375 command line. Also, the '--strict-wildcards' option has been removed
376 and replaced with the inverse option '--nullglob'. See the
377 documentation for wimextract for more details and changes.
379 The wimlib_extract_files() function is now considered deprecated in
380 favor of wimlib_extract_paths().
382 Fixed more permissions problems when extracting files on Windows.
384 A new '--no-attributes' option has been added to wimapply and
385 wimextract. The library flag is WIMLIB_EXTRACT_FLAG_NO_ATTRIBUTES.
387 The default chunk size is now set correctly when changing the
388 compression type of a WIM, for example with 'wimoptimize'.
390 The '--metadata' option to wiminfo has been replaced with the
391 '--detailed' option to wimdir.
393 In relevant wimlib-imagex commands, '--solid' may now be used as an
394 alias for '--pack-streams'.
397 Support for extracting and updating the new version 3584 WIMs has been
398 added. These WIMs typically pack many streams ("files") together into a
399 single compressed resource, thereby saving space. This degrades the
400 performance of random access (such as that which occurs on a mounted
401 image), but optimizations have been implemented for extraction. These
402 new WIM files also typically use a new compression format (LZMS), which
403 is similar to LZMA and can offer a better compression ratio than LZX.
404 These new WIM files can be created using `wimcapture' with
405 the '--compress=lzms --pack-streams' options. Note: this new WIM format
406 is used by the Windows 8 web downloader, but important segments of the
407 raw '.esd' files are encrypted, so wimlib will not be able to extract
408 such files until they are first decrypted.
410 wimlib now supports extracting files and directories from a WIM image
411 based on a "listfile" that itself contains the list of paths to extract.
412 For `wimextract', the syntax is to specify @LISTFILE instead of a PATH,
413 and for the library itself, the new APIs are wimlib_extract_pathlist()
414 and wimlib_extract_paths(). Path globs containing wildcard characters
417 For searching WIM files, wimlib now has configurable case sensitivity.
418 The default on Windows is still case-insensitive and the default on
419 UNIX-like systems is still case-sensitive, but this can be overridden
420 on either platform through flags to wimlib_global_init(). For
421 `wimlib-imagex', the environmental variable WIMLIB_IMAGEX_IGNORE_CASE
422 can be set to 1 or 0 for case-insensitive or case-sensitive behavior,
425 Support for compression chunk sizes greater than the default of 32768
426 bytes has been added. A larger chunk size typically results in a better
427 compression ratio. However, the MS implementation is seemingly not
428 compatible with all chunk sizes, especially for LZX compression, so the
429 defaults remain unchanged, with the exception of the new LZMS-compressed
430 WIMs, which use a larger chunk size by default.
432 The compression/decompression API exported by wimlib has been changed.
433 Now one set of functions handles all supported compression formats.
435 `wimcapture' and `wimappend' will now display the progress of scanning
436 the directory tree to capture, in addition to the progress of writing
437 data to the WIM. The '--verbose' option no longer does anything. The
438 library API change for this is the addition of several members to
439 `struct wimlib_progress_info_scan' available to progress callbacks.
441 `mkwinpeimg' now correctly handles the '--start-script' option when the
442 start script is not in the working directory.
444 Sequential extraction, previously requested by using
445 WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default.
446 WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old default
447 behavior (extract in file order).
450 The new LZX compressor added in v1.5.2 has been improved and is now
451 enabled by default, except when `wimcapture' or `wimappend' is run
452 *without* the '--compress' option, in which case the faster LZX
453 compressor is used (the same as before). This behavior is reasonably
454 consistent with ImageX which actually uses "fast" (XPRESS) compression
455 by default. In those cases, use '--compress=maximum' to explicitly
456 capture a WIM image using the new (slower but better) LZX compressor.
458 The '--compress-slow' option still exists to `wimlib-imagex optimize',
459 but its new behavior is to tweak the new LZX compressor even more to
460 produce an even better compression ratio at the cost of more time spent
463 `wimlib-imagex optimize' now supports the '--compress=TYPE' option,
464 which recompresses the WIM file using the specified compression TYPE.
465 The new library API function used for this is
466 wimlib_set_output_compression_type().
468 Added the wimlib_get_xml_data() function to allow library clients to
469 easily retrieve the raw XML data from a WIM file if needed.
471 Fixed a bug that could cause an error code to be incorrectly returned
472 when writing XML data containing a <WINDOWS> element.
474 Mounted WIM images will now correctly show the default file stream even
475 if appears in the alternate data stream entries of the corresponding WIM
479 Added a new experimental LZX compressor which can be enabled by passing
480 '--compress-slow' to `wimlib-imagex capture' or `wimlib-imagex
481 optimize'. (The latter is only applicable if the WIM is already
482 LZX-compressed and the '--recompress' option is also given.) The
483 experimental compressor is much slower but compresses the data slightly
484 more --- currently usually to within a fraction of a percent of the
485 results from WIMGAPI/ImageX.
487 A workaround has been added for compatibility with versions of WinPE
488 that interpret alternate data stream entries in the boot WIM
491 An alignment bug that caused a crash in the LZX decompressor on some
494 wimlib now attempts to clear the WIM_HDR_FLAG_WRITE_IN_PROGRESS flag in
495 the WIM header when restoring the previous state of a WIM it failed to
498 Added a workaround to avoid an access denied error on Windows when
499 replacing a WIM file that another process has opened.
502 wimlib can now open WinPE WIMs from WAIK v2.1, which had a quirk that
503 needed to be handled.
505 A bug in the interpretation of negative IMAGE indices in the
506 --update-of=[WIMFILE:]IMAGE option to `wimlib-imagex capture' and
507 `wimlib-imagex append' has been fixed.
509 A workaround has been added to successfully apply security descriptors
510 with empty DACLs when the NTFS-3g apply mode is being used with NTFS-3g
511 2013.1.13 or earlier.
513 `wimlib-imagex capture' can now accept the '--delta-from' option
517 Added support for "pipable" WIMs. Pipable WIMs allow capturing images
518 to standard output and applying images from standard input, but they are
519 not compatible with Microsoft's software and are not created by default.
520 See the documentation for --pipable flag of `wimlib-imagex capture' for
523 To better support incremental backups, added support for declaring an
524 image as a modified form of another image. See the documentation for
525 the '--update-of' option of `wimlib-imagex append' and `wimlib-imagex
528 Added supported for "delta" WIMs. See the documentation for the
529 '--delta-from' option of `wimlib-imagex capture'.
531 The library support for managing split WIMs has been changed to support
532 other arrangements, such as delta WIMs, and be easier to use. This
533 change is visible in `wimlib-imagex', which also can now accept the
534 '--ref' option multiple times, and also now supports "delta" WIMs as
537 wimlib now preserves WIM integrity tables by default, even if
538 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
539 behavior of `wimlib-imagex' whenever the WIM being operated on contains
540 an integrity table and the '--check' option is not specified.
542 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
543 (when --compress is not specified). This provides the best compression
544 ratio by default, which is usually what is desired, at a cost of some
547 `wimlib-imagex' now supports being invoked as wimCOMMAND, where COMMAND
548 is the command as in `wimlib-imagex COMMAND'; for example, it can be
549 invoked as `wimapply' as an alternative to `wimlib-imagex apply'. The
550 appropriate hard links are created in UNIX installations of
551 `wimlib-imagex', while for the Windows distribution of `wimlib-imagex',
552 batch files that emulate this behavior are generated.
554 Security descriptors are now extracted correctly on Windows.
556 Fixed archiving DOS names in NTFS-3g capture mode.
558 The extraction code has been rewritten and it will now be easier to
559 support new features on all supported backends (currently Win32, UNIX,
560 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
561 now supported on all backends, not just UNIX.
563 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
564 than the WAIK itself.
566 wimlib_global_init() now, by default, attempts to acquire additional
567 privileges on Windows, so library clients need not do this.
569 This update bumps the shared library version number up to 9, since it is
570 not binary compatibible with previous releases.
573 Fixed bug in `wimlib-imagex export' that made it impossible to export an
574 image from a WIM that is readonly at the filesystem level.
576 Return error code rather than segfaulting when trying to list files from
577 a non-first part of a split WIM.
579 Joining a WIM will now preserve the RP_FIX and READONLY flags.
582 On Windows, paths given to wimlib-imagex are now treated case
585 Improved behavior regarding invalid filenames; in particular, on
586 Windows, wimlib-imagex will, when extracting, now omit (with an option
587 to override this default) filenames differing only in case, or filenames
588 containing characters not valid on Windows.
590 On Windows, wimlib now supports capturing and extracting long paths
591 (longer than the so-called MAX_PATH).
593 On Windows, `wimlib-imagex update' now acquires proper privileges when
594 running as an Administrator.
596 `wimlib-imagex update' will now complain if no image is specified when
597 trying to update a multi-image WIM.
599 `wimlib-imagex update' now supports specifying a single update command
600 directly on the command line using the --command option.
602 wimlib-imagex will now choose different units for progress messages,
603 depending on the amount of data that needs to be processed.
605 `wimlib-imagex append' will now generate a unique WIM image name if no
606 name is specified and the defaulted name already exists in the WIM.
608 wimlib now allows you to create unnamed WIM images, which can then only
609 be referred to by index.
611 wimlib now allows you to explicitly declare you want write access to a
612 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
615 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
618 Progress callbacks have been added to wimlib's wimlib_update_image()
621 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
622 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
625 NTFS-3g capture now only warns about two conditions previously treated
628 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
631 wimlib now correctly detects and returns an error when reading a WIM
632 image with a cyclic directory structure. (Fun fact: such a WIM will
633 crash Microsoft's software.)
636 Added new "extract" and "update" subcommands to wimlib-imagex, along
637 with associated APIs in the library. These commands are intended mainly
638 for Windows use but can be used on UNIX as well.
640 Many documentation improvements.
642 Fixed a bug in the Windows build where relative symbolic links were not
643 captured in reparse-point fixup mode.
645 Fixed a bug in the Windows build where file handles were left open to
646 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
648 Fixed a bug in the Windows build of wimlib-imagex where globbing
649 split-WIM parts could cause the program to crash.
651 Fixed a bug where the creation time of WIM images would be shown instead
652 of the last modification time.
654 With the Windows build it is now possible to restore a WIM containing
655 symbolic links as a non-Administrator; however you will receive warnings
656 about not being able to extract the symbolic links.
659 Capturing a WIM image should now be significantly faster in most cases
660 due to improved use of the operating system's cache and avoiding reading
661 files twice whenever possible.
663 The Windows build should now work on Windows XP.
665 The Windows build now supports capturing and restoring hidden,
666 compressed, sparse, and encrypted files.
668 The Windows build now supports capturing and applying WIM images from
669 filesystems other than NTFS (with some reduced functionality).
671 The Windows build now extracts short names correctly.
673 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
674 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
675 capture' and `wimlib-imagex apply'.
677 The performance of splitting and joining WIMs should be slightly
680 The LZX and XPRESS compression and decompression functions are now
681 exported from the library.
684 Improvements and bugfixes for the Windows build.
686 Added --strict-acls options.
688 Fixed the way that wimlib determines the order of images in the WIM.
691 Since wimlib can now be used on Windows, wimlib's implementation of
692 ImageX has been renamed to wimlib-imagex to avoid confusion with
693 Microsoft's implementation of ImageX, which would have the same file
694 name ("imagex.exe"). If you really don't like this you can pass the
695 --with-imagex-progname option to `configure' to choose a different name,
696 or even simply rename the binary yourself (but the former way will
697 configure the man pages to use the chosen name).
699 Various bugs fixed in the Windows build. Mainly to do with capturing
700 and restoring alternate data streams correctly in weird cases, and
701 requesting the correct privileges when opening files. Also added the
702 --noacls options to wimlib-imagex capture, append, and apply.
704 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
705 dynamically loaded, so this may make the library compatible with Windows
706 XP (however, there may still be other problems).
709 Added experimental support for native Windows builds. Binaries can be
710 downloaded from the SourceForge page.
712 --source-list option added to `imagex capture' and `imagex append'.
714 Better support for different character encodings.
717 Storing UNIX file owners, groups, and modes in WIM images is now
718 possible using `imagex capture' with the --unix-data flag.
720 Minor bug fixes and documentation fixes.
723 NTFS capture: Fixed capturing duplicate reparse points.
725 NTFS capture: Capture first unnamed stream if there are more than one
726 (print warning instead of error).
728 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
731 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
734 Update to work with ntfs-3g version 2013.1.13.
737 Fixed truncating file to shorter but non-zero length on read-write
740 Various code cleanups and minor documentation fixes.
743 LZX and XPRESS decompression have received some additional optimizations
744 and should now be even faster. (Although, they were already pretty
745 fast--- much faster than typical I/O speeds.)
747 Fixed a bug introduced in v1.2.1 that would cause a directory tree
748 containing hard links to be captured incorrectly in some cases.
751 By default, unmounting a read-write mounted WIM with 'imagex unmount
752 --commit' will now change the WIM in-place without needing to write the
753 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
756 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
757 for a response from the daemon servicing the mounted WIM. Instead,
758 every second 'imagex unmount' will check if the daemon is still alive,
759 and keep waiting if so, otherwise terminate with an error.
761 'imagex unmount --commit' on a read-write mounted WIM will now print
762 progress information regarding the writing of new or modified streams
763 the WIM, just like when capturing or appending a WIM.
765 A small change has been made to XPRESS compression and it should improve
766 the compression ratio slightly.
768 A change was made that may improve performance slightly when applying a
769 WIM image to a NTFS volume.
771 Microsoft has managed to introduce even more bugs into their software,
772 and now the WIMs for Windows 8 have incorrect (too low) reference counts
773 for some streams. This is unsafe because such streams can be removed
774 when they are in actuality still referenced in the WIM (perhaps by a
775 different image). wimlib will now work around this problem by fixing
776 the stream reference counts. This is only done when wimlib_delete_image() is
777 called ('imagex delete') or when wimlib_mount_image() is called with
778 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
779 requires reading the metadata for all images in the WIM, so this will
780 make these operations noticably slower on WIMs with multiple images.
782 Various other bugfixes.
785 Appending images to a WIM is now be done by default without re-building
786 the whole WIM. Use the --rebuild flag to get the old behavior (which
787 was to re-build the entire WIM when a new image is appended).
789 A new command `imagex optimize' is now available to manually re-build a
790 WIM that has wasted space due to repeated appends.
792 Progress information has been improved, and now arbitrary callback
793 functions can be used to show the progress of a WIM operation.
795 A possible bug with changing the bootable image of a WIM was fixed.
797 Some advisory locking is now done to prevent two processes from
798 modifying a WIM at the same time (but only in some cases). For example,
799 you cannot mount two images from a WIM read-write at the same time.
801 Some functions have been reorganized:
802 * wimlib_mount() renamed to wimlib_mount_image().
803 * wimlib_unmount() renamed to wimlib_unmount_image().
804 * wimlib_overwrite_xml_and_header() removed as
805 wimlib_overwrite() suffices now.
806 * wimlib_apply_image_to_ntfs_volume() removed as
807 wimlib_extract_image() suffices now.
808 * wimlib_add_image_from_ntfs_volume() removed as
809 * wimlib_add_image() suffices now.
811 Previously, the soname of libwim.so has been 0.0.0, despite many
812 interface changes. The soname is now updated to 1.0.0 and will now be
813 updated each release.
816 Resources will now be compressed using multiple threads by default.
817 (This applies to `imagex capture', `imagex append', and `imagex
820 Some performance improvements in mounted WIMs.
822 More progress information is shown when capturing a WIM.
825 Lots of minor fixes, code cleanups, and some documentation updates.
826 Nothing in particular is really noteworthy.
829 LZX and XPRESS compression improvements.
831 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
832 Link Bytes of the WIM.
835 Fixed bug when capturing NTFS file with multiple named data streams.
837 Internally, we are now using inode structures, even though these don't
838 appear literally in the WIM file. This simplifies some of the code
839 (mainly for WIM mounting) and likely fixed a few problems, although it
843 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
847 Enough changes to call it version 1.0.0!
849 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
850 to a NTFS volume, is now supported.
852 Hard links and symbolic links have much improved support. They are
853 supported for WIM capture, WIM application, and mounted WIMs (you can
854 even make them on read-write mounted WIMs).
856 Alternate data streams are now supported on mounted WIMs through an
857 xattr or a Windows-style stream interface. Also they are supported when
858 capturing a WIM from NTFS or applying a WIM to NTFS.
860 Split WIMs are better supported. You may now apply an image directly
861 from a split WIM, mount an image from a split WIM read-only, or export
862 an image from a split WIM.
864 Using a capture configuration file is now supported (but not fully yet).
866 SHA1 message digests are checked in more places, so we can make sure
867 applied and captured data is correct.
869 Man pages have been updated and consolidated.
872 Fixed segfault when unmounting read-only WIM.
875 Support for joining and splitting WIMs.
876 Also, security data is now preserved by default.
879 Can now build with older gcc and system headers, like on CentOS 5.
882 Fixed bug that made it impossible to overwrite files in read-write
886 Write byte-order mark before WIM XML data. (imagex.exe requires this to
